Transcript of Engineering Design Session-2(Multidisciplinary Nature of Engineering Design)

1. Construct the circuit as shown in the circuit diagram
2. Verify the connection connection
should be verified by
both the members of the team and any one of the faculty
3. Connect the primary of transformer to AC mains supply.
4. Connect the black probe to COM and Red probe to V Ω mA
5. Connect the multimeter across load resistor RL
6. Record the output voltage.
7. Switch off the AC mains supply.
8. Remove the connection and components properly.
9. keep all the components in given box

Multidisciplinary Nature of Engineering Design
Centre for Engineering Education Research
K L E Technological University Hubballi 31
Multidisciplinary field of
Electronics
Mechanical
Coordinated by a
control architecture
Mechatronics system components
Activity-2
DC Regulated Power Supply

At the end of the topic the student should be able to:

Explain engineering design process
Formulate problem definition for the need statement
Generate possible design alternatives/ solutions
:Topic Learning Outcomes:

Internal Connections of the Breadboard
LESSONS LEARNED ???
:Learning from this activity are:


Introduction to the electronic components

Getting familiar with the Breadboard operation

Building regulated dc power supply

Breadboard
Breadboard internal view
Identify multi-disciplinary facet of design
Construct proposed simple mechanical/mechatronic systems
List Engineering disciplines for given designs
Solution:
Photocopying Machine example
Now let us Watch a video of various sensors , actuators and other components involved in Copy machine
Most of the electronics devices uses DC and 5 volts. But Electrical energy available is AC, 230 volts
Power Supply Circuit
R1= 1kΩ RL= 69Ω (22+47)

R= 157 Ω (100+47+10)
What is the power input for most of the electronic devices.? (Example: Mobile)
How do we convert AC to DC?
Problem: How can we convert 230 volt AC to 5 volt DC?
Draw the block diagram.
Digital Multimeter
Digital Multimeter with probes
What is Mechatronics?

Experimental Setup made during design
Do's:
1. It is very important to check the polarity of diodes(IN4007), diode capacitor before placing components on the breadboard.
2. Check proper resistor values.
Dont's:
1. Do not power the circuit without faculty consultation.
2. After powering the circuit do not touch any of the circuit components.
3. Do not remove any component before switching off the supply
Inherently multi-disciplinary
Activity-1
ACTUATORS
SENSORS
Produce motion or cause some action.(Example: DC motor, Stepper motor)
Detect the state of the system parameters, inputs and outputs.(Examples: Switch,potentiometer)
INPUT SIGNAL CONDITIONING AND INTERFACING
Conditioning and interfacing circuits provide connections between the control circuits and the input/output devices.(Examples: ADC )
MECHANICAL SYSTEM
DIGITAL CONTROL ARCHITECTURE
Digital devices control the system.(Examples:Logic circuits, PLC)
OUTPUT SIGNAL CONDITIONING AND INTERFACING
GRAPHICAL DISPLAYS
Conditioning and interfacing circuits provide connections between the control circuits and the input/output devices.(Examples: DAC)
Graphical displays provide visual feedback to users.(Examples:LED, LCD)
